To all wwm 'it may concern:

Be it known that I, Winnian Koirrnn, Jr.,` a citizen of the United States, and a resi dent of Brinkman Ridre, in the county of Vernon and State of Visconaim have iiivented a new and Improved Counterlnilanre I' `for later-Pumps, ,of which the following is a full,'clear, and exact description.

The purpose. of this invention is to provide novel features of construction for a counterbalance that is an attachment for a water pump, which will balance the weight of the puni) rod. and the bucket on it, and of water lifted by the rod and buclt'et, thusreducing'labor in operating a pump having the improvement placed thereon.

The invention consists iii the novel construction and combination of parts, as is hereinafter described and defined in the appended claims;y

Reference is to be had to the. accompanying drawings .forming a part of-thls specilication, in which similar charactersof reference indicate corresponding parts in all the views.

Figure 1 is a side view of a'puiiip erected for service, and having the improvement thereon; Fig. l is an enlarged sectional front view of the improvement., seen iii the diret tion ot the'arrow a: in Fig. 1; and Fig. :l is a sectional plan view ot' details, taken sulstantially on theline 3-3 in I"ig. 2.

The invention is designed for use ou a well-known, class of water pumps that may be used foi\ raising water inaiurallv or bv other power. from 'wells of i'litl'erciit deptlis and lessen the labor required in the operation of the saine.

In the drawings, 5 indicates the barrel and 5" the upper water chamber of a vpump of ordinary construction. said chamber having a reduced cylindrical open upper end a .as usual. A rod wliereon a bucket of any preferred construct-ion is atlixed at its lower end, extends centrally upward through the barrel 5 and chamber 5*, and a't a suitable distance above. the chamber the upper portion of said rod has a rectangular body t3 as shown iii Fig. 2.

The improved wunterbalance device that is mounted for service on the upper cndor collar a of the chamber 5., comprises the fol- 'lowingdetailsz A base plate 7 consisting of a mainly flat metal body, -is provided with a circular dependinv flange b, that proects centrally from the ower side thereof, iav- Speccation of Letters Patent.'

ing an interior diameter that loosely receives the collar a wliereon said flange is mounted and. secured by one or more set screws c, as shown in Fig. 1. The base plate T is centrally perforated for the free passage ofthe pump'rod G upwardly through it, and at opposite points therefrom said base plate is extended, these extensions having similar spring' casings 8 erected thereon that a re. equally distant from the pump rod. 'lhc spring casiugs 8 are hollow cylinders of suitable dimensions. The base vplate 7 is strengthened byl the webs a that are formed on the base plate .and flange-71. In the same vertical plane with the axis of the pump rod 6 and diametrically opposite' each other, two

lonfritudiiial .slots (i, d, areformed in `the wall. of each spring casing 8, said slots extending from near the lower ends of the casing's to neartlieir upper ends, as is shown 'in Fig. 2. ik circular guide plate 9 is loosely itted iii each spring casing 8, each of said plates having two diai'netrically opposite ears e, c, formed thereon which project outward through the respective slots d, d, when the -giiide plates are placed within the casiiigs. In each casing S, a strong coiled spring 10 is introduced from the upper end thereof, and is-seatcd on a respective guide plate Sl. said springs having an equal length that adapts ltlieui to extend to nearly the height. of the slots (l and their diameter is such thaty they lit loosely within the casings. yoke piece 11, preferably bent at its center iiito substantially U-shape, is formed at said .eenter with an iiiteg'al circular collar y, wherein a sleeve li, is fitted and secured by a set screw i, said sleeve having)` a rectangular vertical o iening tliereinvw iich receives the square body portion t'i"` of the pump rod G, int-o which the set screw 1' is also inserted, as is indicated by dotted lines in Fi 3. F roiii the U-shapcd central portion o the yoke piece 11, two arms m, m' are oppositely extended, which pass thi'ou li the slotsl Il in` the respective casings 8, sai arms each liaving,y a lateral concavity n formed therein. ln each spring casing 8, at the center of the guide plate 9, a stein'tl extends u ward from said guide plate, and is of a4 ength that ada )ts it to project a distance above the upper edge of the casing. each stem passing loosely through a respective concavitv 'n iii the horizontal arm 171,7 thus affording clearance for the arms m. Upon each spri-n 1t), a centrally perforated disk 12 is seate v formed that is mounted uppnV a respective stem ,595 and upon each dis a respective arm m, imposed as shown in Fi at each end thereof a collar -o which loosely encircles the upper end of a corresponding casing 8, and concentric with each collar an opening p is formed in an end portion of the cap plate, through which extends the upper portion of a respective stem 9, said ends of the stems being threaded for the reception of clamping 4nuts r that are screwed thereon and bear upon the cap plate. At the center of the cap plate 13, a circularopening is formed wherein the body of a guide box s. is fitted and secured b aA set screw s', and has a rectangular opening through which the rectangular' portion Ga ot' the rod 6 is upwardly/extended and adapted for reciprocation. Two spaced ears 'v are at one side on the depending fiange b, receivirg between them the lower end of a link bar w that is ivoted vthereto and thence projects 4u ward y. y Upon the rod 6, the upper end' o a handle leverletis `pivoted, andy thence curves outward and down'- ward, and as shown in Fig. 1 the upper end of the link bar 'w is lapped and pivoted upon said lever.

In case the pump and improvements so4 far as described, are to be placed over a we'll of moderate depth,'so thatthe pump rod 6 is of moderate length, the tensionalforce of the Ysprings 10 will compensate for the weight of the pump rod, and of the water lifted by a depression of the fr ee end of the handle lever 14 and a corresponding upward movement of said rod, and water'that 1s discharged from a spout 5b on the chamber 5. When the pump and improved counterbalance device is ,to be used for the lifting of water from a well fof considerable depth,

additional counter-balancing means are em-V ployed that cooperate withv that already del' scribed, said supplementary means consisting of the following details: The ears e, e, )roject from each o the guide-plates 9, sufy ciently for the reception and support of a flat metal base ring 15, and upon each base ring 15 a spiral spring 16 is seated, said springs respectively encircling a corresponding casing There' is an annular bearing rm spring 16 and t eheight ofthe latter is equal with that of'the springs 10, so that the end portions of the'arms m, m, will bear upon the springs 10 and 16 with equal force. It will-be evident. that the coperation of the springs 16 with the springs l0, willadd to the support of a pump rod ,of increased length and the each upward stroke of said rod, so that the manual labor performed in working a water pump in a deep well or one of lessdepth, may be reduced to a minimum by the emg. 2. A laterallyelongated cap plate 13 is provided, havin-g- 17 seated u on the upper end of each' weightof water lifted at' device. v lt 1s` apparent that either the outer set of Vpleyment of the improved counterbalancing springs or the inner set thereof ma be dis-V claim as new and desire to secure by Letters,
